PORTABLE ELECTRIC LUMIBER.y ANTD TIMBER GRADE-MARKING DEVICE.

Application filed July 6.

The presentin'vention relates to a device for marking suitable indiciaon lumber and tii'nber to indicate the grade thereof and has for itsprincipal object to provide a device of this nature which iselectrically heated so as te burn the indicia into the lumber er timber.

Another important object of the invention is to provide a device of thisnature which is portable, simple in construction, strong, durable, easyto handle, eilicient and reliable in use, and otherwise well adapted tothe purpose for which it is designed.

lVith the above and numerous other objects in` view as will appear asthe description proceeds, the invention resides in certain novelfeatures of construction, and in the combination and arrangement ofparts as will be hereinafter more fully described and claimed.

In the drawing- Figure 1 is a sectional view taken through the deviceembodying the features of my invention,

Fig. 2 is another sectional view therethrough at right angles to thatshown in Fig. 1.

Fig. 3 is a plan view of a guard used with the device,

Fig. 4 is an elevation of said guard, and

Fig. 5 is a detail view showing a holder and stencil which areseparable.

Referring to the drawing in detail it will be seen that 5 designates ahandle having a tubular shank 6 extending therethrough adapted toreceive an electric cord. A head 7 is formed on the end of the shank 6and has a depending flange portion 8 to which is bolted as at 9 a coreplate 10 having formed on its end a stencil 11. Binding posts 12 aremounted in the upper portion of the core plate 10, being insulatedtherefrom in any suitable manner as is indicated in dotted lines at 13and to which are attached the conductors of the electric cord passingthrough the hollow shank 6. Suitable electric heating elements 14 aredisposed about the core 10 and connected with the binding posts 12. Acasing 15 is disposed about the heating elements 14 and houses thecasing 7 attached to said head by screws 16. The lower edge 0f thecasing rests on the upper portion of the stencil 11. The stencil 11 isprovided with suitable indicia so that when the core 10 is heated by theelectric heating elements 14,

said indicia may be burnt into lumber or timber.

lf desired, the core 10 may be formed with a grooved head 17 to receivea removable stencil 18, Figure 5. A guard is disposed about the shank 6between the handle and the head and consists of a hub 19 for receivingthe shank, this hub 19 being engaged with the shank by a set screw 20. Aplurality of spokes 21 radiate from the hub 19 and support a ring Q2concentrically about the hub. This shield allows the device to besupported on its side with the hot stencil out of the way so as toprevent the same from coming intocontact with wood or other inllaminablematerial accidentally.

1t is obvious, of course, that the ring 22 may be constructed of apolygonal formation if desired. The present embodiment of the inventionhas been disclosed in detail merely by way of example since in practiceit attains the features of advantage enumerated as desirable in thestatement of the invention and the above description. It will beapparent that numerous changes in the details of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what l' claim as new isz- 1. Adevice of the class described including a tubular shank, a handle on theshank, a head formed on the end of this shank, a core bolted to thehead, a stencil on the core at the end thereof remote from the head,electric heating elements disposed about the core, a casing disposedabout the electric heating elements and about the head, and a guarddisposed about and at right angles to the shank and between the handleand the casing and spaced from the heel portion of the casing.

2. A device of the class described including a shank, a core on theshank, a stencil on the core at the end thereof remote from the shank,electric heating means about the core, a hub disposed on the shank,spokes radiating from the hub, and a ring yon said spokes; said hub,spokes and ring spaced from the heel portion of the heating means.

3. A device of the class described including a tubular shank, a handleon the tubular shank, a hub on the tubular shank, a set screw in he hubto lock the hub to the Shank, spokes radiating from the hub, 2L ring outhe Spokesfa head on the shank at die opposite side of the hub, withreference 0 the handle, a flange extending from the head, a coie boltedto the Harigea a stencil et the end of the core remote from said headelectric heating elements about the Core, and binding posts on the Coreconneeted to the electric heating elements, said 10 tubula shank adaptedto receive an elec trie Cord with its Conductors attached to the bindingpost, and ay casing disposed about the eieoti'ic heating elemente and hehead.
